Assertion:
In Griffith's experiment, mice were injected with a mixture of heat killed Smooth type bacteria and live Rough type bacteria. Some mice died of pneumonia and their blood contained both live Rough type bacteria and live Smooth type bacteria.

Reason:
The dead Smooth type bacteria became alive and caused pneumonia. Griffith named it as the transforming principle.

Explanation:
- Griffith's Experiment: In Griffith's experiment, he observed that when he injected mice with a mixture of heat-killed Smooth type bacteria and live Rough type bacteria, some mice died of pneumonia.
- Presence of Live Bacteria: Upon analyzing the blood of the mice that died, Griffith found both live Rough type bacteria and live Smooth type bacteria present.
- Transforming Principle: Griffith hypothesized that something from the heat-killed Smooth type bacteria had transformed the live Rough type bacteria into a virulent form, causing pneumonia in the mice. He termed this phenomenon as the transforming principle.
- False Reason: The reason stated in the assertion that the dead Smooth type bacteria became alive and caused pneumonia is not accurate. It was not that the dead bacteria became alive, but rather something from the dead bacteria transformed the live Rough type bacteria.
Therefore, the assertion is true as Griffith did observe the mentioned outcomes in his experiment. However, the reason provided for the assertion is false as it does not accurately explain Griffith's findings.
